There are three sets of Shado-Pan daily quests:
- Omnia Mystics: Shan'ze Dao (northern most island)
- Wu Kao Assassins: Sra'vess (western most island)
- Blackguard Defenders: Deadtalker's Plateau and Fire Camp Gai-Cho (mainland)
You must have the Choose a Shado-Pan Companion debuff while handing in the quests to satisfy the achievement's criteria. You will lose this debuff upon leaving the zone. To reacquire it, you must first abandon one of the quests and then reaccept it.
Each set of daily quests offer an additional quest after the completion of those that are initially given. You'll receive credit after turning this quest in.
